CVE-2005-0454 in DCP-Portal
Summary
by MITRE
Multiple SQL injection vulnerabilities in DCP-Portal 6.1.1 and earlier allow remote attackers to execute arbitrary SQL commands via (1) the lcat, doc, or uid parameters to index.php, or (2) the mid or bid parameters to forums.php.

The vulnerability described in CVE-2005-0454 represents a critical security flaw in DCP-Portal version 6.1.1 and earlier systems, specifically targeting SQL injection attack vectors that enable remote code execution. This vulnerability falls under the common weakness enumeration CWE-89 which categorizes SQL injection as a serious weakness in software applications that process untrusted input through database queries. The affected software DCP-Portal, a content management system, fails to properly validate or sanitize user input before incorporating it into database queries, creating an exploitable condition that can be leveraged by malicious actors from remote locations.
The technical implementation of this vulnerability occurs through multiple entry points within the application's codebase, specifically targeting parameters in two distinct PHP files. The primary attack vectors involve the lcat, doc, and uid parameters within the index.php file, as well as the mid and bid parameters within the forums.php file. These parameters are directly incorporated into SQL queries without proper input sanitization or parameterized query construction, allowing attackers to inject malicious SQL code that gets executed by the database server. This type of injection vulnerability is particularly dangerous because it can be exploited to bypass authentication mechanisms, extract sensitive data, modify database contents, or even execute operating system commands depending on the database backend and privileges available.
The operational impact of this vulnerability extends beyond simple data compromise, as it provides attackers with a pathway to gain unauthorized access to the underlying database infrastructure. When exploited successfully, these SQL injection flaws can result in complete database compromise, allowing attackers to read sensitive information such as user credentials, personal data, and system configurations. The remote nature of the attack means that no local system access is required, making the vulnerability particularly attractive to threat actors who can leverage it from anywhere on the internet. According to ATT&CK framework category T1190, this represents a network service exploitation technique that can be used to establish persistent access to target systems, while also aligning with T1071.004 which covers application layer protocol manipulation. The vulnerability affects the confidentiality, integrity, and availability of the affected system, potentially leading to complete system compromise and data breaches.
Mitigation strategies for this vulnerability must address both immediate remediation and long-term security improvements. The primary solution involves upgrading to a patched version of DCP-Portal that implements proper input validation and parameterized query execution. Organizations should also implement web application firewalls to detect and block malicious SQL injection attempts, while applying proper input sanitization techniques such as escaping special characters and using prepared statements. Security measures should include regular vulnerability assessments, code reviews focusing on database query construction, and implementing the principle of least privilege for database accounts. Additionally, monitoring systems should be deployed to detect unusual database access patterns that might indicate exploitation attempts, and incident response procedures should be established to quickly address any successful breach attempts. The vulnerability demonstrates the critical importance of secure coding practices and input validation in preventing database-level attacks that can compromise entire system infrastructures.
